Mala did some testing on this a couple of weeks back. It appears that
NAPI damaged performance significantly.

http://www-124.ibm.com/developerworks/opensource/linuxperf/netperf/results/july_02/netperf2.5.25results.htm

Unfortunately it is not listed what e1000 and core NAPI
patch was used. Also, not listed, are the RX/TX mitigation
and ring sizes given to the kernel module upon loading.

Robert can comment on optimal settings

Robert and Jamal can make a more detailed analysis of Mala's
graphs than I.
